Provided are a battery module and an energy storage device. The battery module includes cylindrical cells arranged in at least two rows and a liquid-cooled assembly including at least one liquid-cooled unit each including a liquid-cooled tube and a cooling fin; the liquid-cooled tube includes a first tube arranged at an upper end of the cooling fin, a second tube, and a third tube arranged at a lower end of the cooling fin; the second tube connects one end of the first tube with one end of the third tube; the cooling fin is arranged between two adjacent rows and is connected to circumferential side surfaces of cells in the two adjacent rows; the first tube and the third tube each have an opening defined in another end thereof facing away from the second tube.

Battery module and energy storage device

Provided are a cover assembly for a battery and a battery. The cover assembly for the battery includes an elastic cover, an insulating cover, a frame support member and a terminal column assembly. The insulation cover is embedded in one end of the elastic cover. The frame support member has a greater hardness than the elastic cover and the insulating cover. The frame support member is embedded in the other end of the elastic cover. The elastic cover has an encapsulation portion disposed on an outside, in a radical direction, of the insulating cover and the frame support member. The encapsulation portion is in a cylindrical shape and configured to abut against an inner surface of a housing of the battery. The terminal assembly includes a terminal penetrating the insulating cover and the elastic cover.
